| 30 | | - * s/he should set $wgEnableAPI to true and exits. Otherwise, it constructs |
| 31 | | - * a new ApiMain using the parameter passed to it as an argument in the URL |
| 32 | | - * ('?action=') and with write-enabled set to the value of $wgEnableWriteAPI |
| 33 | | - * as specified in LocalSettings.php. It then invokes "execute()" on the |
| 34 | | - * ApiMain object instance, which produces output in the format sepecified |
| 35 | | - * in the URL. |
